Best MTB Hydration Pack [2022]

Using hydration packs while riding a mountain bike has many benefits. 

The benefits of using a mountain bike hydration pack include being able to drink as you ride, being able to carry the key essentials like tools and spare parts, and not having to stop or take your hands off the handlebars when you need to drink. 

After looking at the vast collection of hydration packs, we have picked the twelve best hydration systems for mountain biking, considering water and storage capacity, durability, accessibility, style, and comfort.

We reviewed each of the different categories and picked our favorite. Those categories include day packs, multi-day packs, hip packs, lumbar packs, vest packs and packs for women and children.

The Best MTB Hydration Pack

We chose the Osprey Raptor 14 as the overall best mountain bike hydration pack for mountain biking because it has a high-quality hydration hose with bite valves to access water, a separate removable tool roll, and many other features bikers will love.

The large storage capacity of the hydration bladder and bite valve allow for quick drinks without getting off the MTB or having to stop. The smart design offers an ample amount of storage to keep important tools or snacks.

Overall we could see the amount of effort Osprey put into designing a pack specifically for mountain biking. The excellent material used on this pack, the capacity of the hydration reservoir, and the superb, comfortable design make the Osprey Raptor 14 our favorite product.

Extra pockets on the waist straps for added easy accessNo integrated rain cover
Ventilated back panel keeps your back cool


Osprey Raptor 14 is a lightweight purpose-built premium hydration pack for high-performing riders. It is a very durable product made with high-quality materials and you can feel it when you hold it in your hands.

The zippers and fabric are well made and can withstand the rigors of riding for years to come making it clearly one of the best hydration packs available.

The shoulder, sternum, and waist strap nicely fit at the back and don’t bounce around as you ride. This pack has one of the largest storage capacities of the packs we reviewed with 14 L of space.

The biggest downside to this model is that the quick release hose has been removed from the bladder. This was great for cleaning out the bladder. However, you can buy a separate reservoir by itself and you’ll get a version with the quick release hose.

Evoc Stage 12L – Best Overall Runner-Up

Evoc Stage 12L hydration backpack
Evoc is a great bag with a lot of promise

Key Features

  • Pack: 12 liter storage & gear capacity
  • Hydration: up to 3 liter capacity
  • Multi-purpose backpack that can be used for biking, hiking and more
  • The airflow contact system provides maximum breathability
  • Brace Link shoulder straps
  • Includes integrated rain cover

Brace Link shoulder straps adjust to your shoulder widthCell phone pocket may be too small for some phones
Separate compartment for storing toolsThe side pockets are not zip-covered

Removable waist straps


This mountain bike pack is nicely designed with lots of technical features that are perfect for a day-long trail riding session. 

This pack contains a handy double zipper pulldown compartment on the back of the bag that is designed to carry tools and snacks. 

The backpack does support up to 3 L reservoirs which makes it the largest water capacity of the packs we reviewed. It also has a dedicated hydration sleeve to isolate the water reservoir in case it leaks. Of course, the biggest downside to this pack is that it doesn’t actually include the reservoir so you’ll have to buy that separately. Here’s a link to their bladder: Evoc Hydration Bladder

The integrated rain cover is a great feature if you’re in a climate where it rains, however it was a bit finicky to get back into its compartment after we tried it out.

CamelBak MULE 100 – Best Classic Pack

CamelBak MULE 100 hydration pack
The CamelBak MULE is a classic all around great bag

Key Features

  • Pack: 9 liter storage & gear capacity
  • Hydration: 3 liter capacity
  • Airflow channels on the back panel and shoulders to avoid heat
  • The waist belt is detachable 
  • The sternum strap offers a range of adjustments to ensure a good fit

Good ventilation on back and shouldersThe top cap of the reservoir can leak if not sealed properly
3 L bladder includedNot enough utility pockets
Dedicated section for crux reservoir


The CamelBak MULE is one of the first packs designed specifically for mountain bikers. It is the standard with which new companies benchmark against when designing their packs. 

In addition to mountain biking, we’ve used this for hiking and it’s perfect for a day hike as there’s ample storage space in the pack for snacks and a first aid kit. There’s also an expandable pouch that can be used for storing a jacket in case it rains.

The hose tube on this pack is really durable so it won’t crease or get a kink in it. There’s also a nice hose clip and magnetic snap for storing the tube between drinking sessions.

USWE Airborne – Best for Racing

USWE Airborne hydration pack
This harness-style pack stays snugly in place while shredding the trails

Key Features

  • Pack: 3 liter storage capacity
  • Hydration: 2 liter capacity
  • Advanced NDM race suspension harness 
  • Non-restrictive stretchy straps allow resistance-free motion and fits all sizes
  • Water-resistant media compartment
  • Detachable external pocket for weight reduction
  • High vent shoulder straps are designed to let in cool air for additional comfort
Lightest of the day packs at .91 lbOnly has 3 liters total of storage space
Contains a waterproof compartment for keeping phone dryDoes not have enough internal pockets
Magnetic attachment to lock the hose on the front strapOnce you fill the hydration bladder there isn’t much room for anything else
Straps nicely fit all mountain bikersIn some cases, riders experienced errors in manufacturing
Manufactured using high-quality durable material


The hydration pack offers a unique bounce-free experience by employing an NDM system (NDM stands for “no dancing monkeys”) with stretchy straps that click on the sternum for comfortably keeping your pack between the shoulders.

The last thing you want while zooming down the mountain is your pack moving around on your back. This pack design fixes that. It stays firmly in place and doesn’t move.

The downside to this product is the lack of storage so it won’t be great for long rides that require a lot of extra tools, food, or clothing to take with you. But it’s not made for that. This is one of the best hydration packs for racers.

Dakine Drafter 14L – Best Storage Features

Dakine Drafter 14L
The Drafter has a lot of storage capacity

Key Features

  • Pack: 14 liter storage & gear capacity
  • Hydration: 3 liter capacity
  • Reservoir offers a bite valve with automatic shutoff, magnetic hose clip, and quick-disconnect tubing
  • Air Suspension back panel for regulating temperature
  • Internal e-bike spare battery storage system
  • External helmet carry
Air suspension back panelNot great for everyday use
Breathable ergonomic straps for a cooling effectHip straps are not removable
Internal system to store an extra e-bike batteryHelmet carry is difficult to attach
Multiple internal organizer pocketsWeighs more than competitor products in the market
Offers safety light attachment pointNo rain cover


The most promising feature of this hydration pack is its large capacity in a compact design that fits nicely on the back, causing no hindrance as you explore the mountains.

It has purpose-built pockets with zippers for proper organization but some of them are behind the area where you’d store your helmet. The straps have pockets to provide easy access to sunglasses or snacks to enjoy a continuous ride without stopping.

We had issues with the straps on the hip straps. They are not removable and you can’t really tuck them away anywhere. So, a small gripe, but if you don’t plan on using the hip straps you’ll have to wrap them around the back of the bag.

Osprey Syncro 20 – Best Multi-Day Pack

Osprey Syncro 20 multi day hydration pack
If you need to carry more gear or clothing, this is the pack for you.

Key Features

  • Pack: 20 liter storage & gear capacity
  • Hydration: 2.5 liter capacity
  • Front stretch mesh pocket and scratch-free heat-embossed zippered slash pocket for electronics or glasses
  • Lidlock feature for helmet
  • Blinker light on the front of the hydro pack to keep you safe on the trail
  • Removable high-visibility rain cover in an enclosed pocket
  • Zippered tool organization pocket to keep tools handy
Back ventilation with mesh provides great airflow to limit sweatingHip straps are not removable
Magnetic sternum strapLacks compression straps on the bottom of the bag
Integrated hydration system with a magnetic clip on the chest strapDoes not have a zipper on the side pockets
Several individual pockets to organize gear wellToo big for a single-day trip
A bottom pocket with a dedicated rain cover


This is a large capacity multi-day hydration pack with eight distinct pockets, two side pockets, a pocket on the shoulder strap, and a separate compartment for a hydration reservoir. 

Included rain cover tucks away nicely into the bottom of the pack. The stretchy pockets on the side make it great to carry a flask with you. These features alone make it a handy pack to carry with you on multi-day mountain biking trips.

The way the pockets and zippers are laid out make it really easy to access things that you’ve stored in the bag.

The top handle, between the shoulder straps, makes it easy to carry after rides if you don’t want to wear it on your back.

CamelBak Skyline 10 LR – Best Lumbar Pack

CamelBak Skyline 10 Lumbar hydration pack
This lowrider includes a roll up tool organizer as well.

Key Features

  • Pack: 10 liter storage & gear capacity
  • Hydration: 3 liter capacity
  • Lumbar design to store hydration bladder lower on back
  • The inner belt transfers weight to the hips while the outer belt compresses cargo
  • Hip belt is well ventilated to provide comfort
  • Includes roll up tool roll
  • Lightweight and breathable 3D ventilated mesh harness
  • Secure phone pocket to keep stuff safe and easily accessible
Doesn’t restrict movement like a traditional backpackNot suitable for multi day trips
Weight is balanced off of your shouldersNo outer or side pockets
Well ventilated hip beltNot great for storage of additional mountain biking essentials
Easily accessible pockets
Includes roll up tool organizer


This pack is specifically designed to offer support in the back’s lumbar region for MTB riders on all-day trails. It sits lower on the back and provides hip support, freeing your back from additional strain.

The most strain we noticed was in the pack itself. When we filled it completely full of water, it seemed like the pack was going to fall apart. So if you need to carry a lot of extra mountain bike essentials, this might not be the best MTB hydration pack for you.

The hydra pack has a removable tool roll but not much more space for other stuff. You can utilize the external loops to stow your helmet as well as some armor but you’ll need to make some choices about which to keep wearing and which to attach.

Evoc Hip Pack 3L – Best Hip Pack

Evoc hip pack hydration bag
Durable hip pack with great storage.

Key Features

  • Pack: 3 liter storage & gear capacity
  • Hydration: 1.5 liter capacity
  • Features an airflow contact system for cooling back ventilation
  • Venti strap system allows adjustment for uphill or downhill riding
  • Dedicated compartment for storing tools and other essentials
High-quality, durable material, and smart designSmall mobile phone pocket does not fit big phones
1.5 L hydrapak with a top sealing systemThe waist strap is designed for thin people
Zipper pockets to organize tools and essentialsThe magnetic system for the bite valve isn’t great and falls off
Airflow contact system to avoid heat built upCan’t really carry a lot of stuff for long rides
Elastic strap with buckle for fitting around the waist


If you’re tired of the day packs or don’t need to carry that much water, then a hip pack is a great solution. This hip pack is compact and most suitable for short mountain biking trips. 

The waistband on this pack utilizes a two layer strap. The first, is a wide elastic strap with velcro that attaches beneath the buckle. This makes it very comfortable to wear for long periods of time.

It has storage space to keep important stuff and a dedicated compartment with a zipper pocket to safely place your phone. Additionally, the built-in ventilation system keeps you cool, and it hangs nicely around the hips keeping the weight off your back.

CamelBak Chase – Best Hydration Vest

CamelBak Chase vest
Great lightweight vest from a great brand.

Minimalist design keeps the vest lightweightLacks integrated raincoat
Mesh at the back for airflowNot as much storage for essentials as other packs
Front storage pockets for quick accessDoes not have any tech features
Magnetic hose attachment on the strap


Hydration vests are great because they allow you to keep important stuff up front rather than in the back like traditional day packs. They also have additional storage in the back for stuff that you don’t want falling out which can happen on steep declines.

We found that we didn’t use a lot of the zippered front pockets on the Chase Vest while riding but having easy access to those pockets up front was great when we were stopped.

This vest has dual buckle straps in the front to help keep the vest in place while mountain biking or running. Once you put it on, there’s also two side straps at the bottom that you can use to tighten the vest for a snug fit.

Women no longer have to wear packs that don’t fit well and are made for men. The Raven by Osprey is a woman’s version of one of the best hydration packs on the market. 

This pack has plenty of space to carry necessary tools, gear, snacks, a raincoat or any other essentials. It has a foldable tool organizer in a dedicated pocket to efficiently organize the tools for mountain biking and provide easy access to them. 

The straps are perfectly designed to fit a woman’s upper torso and are made with breathable material to maintain airflow.

Soft and sturdy padded back
Hose with lock system to control water flow to bite valve


This mini-sized pack is the best hydration pack for young MTB riders. It has long adjustable straps to fit kids from 2 to 11 years.

It is a great way to get your kids to drink more water, which is always a good thing. Even if kids lose the bite valve, the hose won’t leak due to an efficient lock system and will continue working.

The only issues we had were with the bladder loop being a little tricky to get on and off. The other issue is that you have to pull the hydration bladder all of the way out in order to fill it.

Buying Guide for the Best MTB Hydration Packs

Read our tips below on what to look for when shopping for the best hydration packs on the market today.

What Is A Hydration Pack?

A hydration pack is a special hydration system molded into a backpack or waist pack. It is designed such that its wearers can drink water without needing to slow down or use their hands as they ride their mountain bike.

A hydration pack has a water reservoir referred to as a hydration bladder for storing water. This bladder has a capped opening for easy refilling and cleaning and a tube and hose system that ends at a bite valve, allowing the wearer to drink water.

In addition to the bladder feature, packs also include versatile features to accommodate biking tools, spare parts, additional clothes, food, or extra gear.

Furthermore, they have multiple straps to ensure it fits nicely on your back as you explore your favorite trails.

Types Of Hydration Packs

There are different types of hydration packs that are widely available. Below is a quick run-through of different hydration packs to help you find the one that suits you best.

Fanny Packs, Hip Packs and Bum Bags

These are the smallest easy-to-carry lightweight packs that fit around the waist. They come with a single strap with a small water bladder and a small storage space for essentials.

Vest Packs

Vest packs are designed to distribute weight and storage more evenly between the front and back of the wearer. Vest packs can also carry a fair amount of water but their storage options are often limited.

Lumbar Packs

These packs are designed to ride low on the rider’s back. This lowers the weight placed on your back but still allows you to carry a decent amount of water.

Day Packs

As the name says, day packs are good to go for a day-long voyage. They have a larger bladder and offer more space to carry essential tools or extra clothing. These are lightweight and easy to carry.

Multi-Day Packs

Multi-day packs are larger, heavier, and offer excellent water and storage capacity to carry stuff for multiple days on the bike. They tend to have sturdier shoulder straps to offset the strain from the extra weight of your belongings.

What To Look For In Mountain Bike Hydration Packs?

Besides the type, many notable features influence the choice of the hydration pack. These features include:

Expandable Storage Capacity

Some hydration packs are more expandable than others. Some come with dedicated pockets to hold your stuff and keep them from shifting while other packs just have larger main compartments.

Water Capacity

Different hydration packs offer different water capacities ranging from 500 ml to 6 liters or even more. Your selection depends on your water requirements, the hydration pack’s storage capacity, and how much it will weigh after filling up.


Manufacturing material affects the durability of the pack. The bladder is made of flexible plastic or rubber, whereas the bag consists of nylon or long-lasting, waterproof materials. The quality of zippers and pulls on the pockets should also be considered.

Hose and Bite Valves

Hose quality and length add to the durability of the hydration system in the backpack. It ensures that the hose does not kink or leak.  Most hoses end at a bite valve as it allows you to drink water without using your hands. A silicon cover covers the bite valve to protect it from dust.

Fit and Comfort

MTB hydration packs vary in shape, style and size. 

Some hydration packs have additional padding on the backside to comfort the back of the biker. Padding brings convenience but also adds to the total weight and can restrict ventilation. 


Hydration packs come in different sizes to accommodate a wide range of mountain bikers. The shoulder strap and waist belt length play a significant role in selecting the correct size. The straps help to keep the MTB hydration packs in place. 

Tech Features

Many packs on the market contain different technical features. These include nifty features like removable tool storage organizers, built-in rain covers, and straps to attach helmets.

How Easy Is It To Clean?

Regularly cleaning your hydration bladder is important to prevent the build-up of bacteria. One way to do this without filling them with water and making them leaky is by wiping them down with a wet cloth for an easy on-the-spot clean. Then be sure to dry it completely.

Final Thoughts

Hydration packs are a great accessory for mountain bikers because they help the riders to stay hydrated without interrupting the ride they’re on.

Hydration packs come in various sizes and integrate multiple functionalities to offer additional benefits for MTB bikers. They feature storage compartments, zipper pockets, ventilated backs, and offer different strap adjustment options to get a great fit.

All these features collectively present a hydration pack that fits nicely on the back, does not bounce, provides ample storage space for important gear and keeps a rider hydrated all through their ride.

After evaluating a number of hydration packs available, we concluded that Osprey Raptor 14 is one of the best hydration packs. It has multiple outstanding features to benefit the riders during their daylong riding sessions.
